- We consider tunneling of quasiparticles through a rectangular quantum well, subject to periodic driving. The quasiparticles are the itinerant charges in two-dimensional and three-dimensional semimetals having a quadratic bandtouching (QBT) point in the Brillouin zone. To analyze the time-periodic Hamiltonian, we assume a non-adiabatic limit where the Floquet theorem is applicable. By deriving the Floquet scattering matrices, we chalk out the transmission and shot noise spectra of the QBT semimetals. The spectra show Fano resonances, which we identify with the (quasi)bound states of the systems.

- The emission of atomic and complex nitrogen ions, which are the main impurity determining the n type conduction of silicon carbide, is investigated. It is shown that, among all the secondary ions of the CxN and SixN kind (x = 0, 1, 2, 3), the (26)(CN)(-) fragment exhibits the highest ion yield. The use of an ion peak with a specified mass as an analytical signal provides a detection limit for nitrogen in SiC at a level of 10(16) cm(-3). This result is attained in measurements at high mass resolution (M/DeltaM = 7500, interference peak (26)(C-13(2))(-)).

Pregnancy and risk of non-Hodgkin´s lymphoma : a prospective study

- The etiology of non-Hodgkin's lymphomas (NHL), including chronic lymphocytic leukemia (CLL), is likely to be related to immune function. In the light of the established immunologic effects of a pregnancy, we decided to examine the risk of NHL and CLL in relationship to full-term pregnancies. Within a nationwide cohort we identified 1,546 women with NHL and 198 women with CLL, all 15 years or older, born 1925-1972. Five age-matched controls were selected for each case patient. Conditional logistic regression was used to estimate the odds ratios after mutual adjustment for number of births and age at first birth. We found a weak, negative association between parity and risk of NHL (p for trend 0.11) and a transient, 10-40% decrease in risk within 5-14 years after the last birth among women with various parity status. The risk of CLL decreased more markedly, and orderly with increasing parity, but the trend was not significant (p = 0.18). Small numbers of cases with CLL prevented more detailed analyses of temporal relationships. Age at first birth appeared unrelated to the risk of both NHL and CLL. We conclude that the immunologic alterations associated with a pregnancy have limited, if any, relevance to the etiology of NHL and CLL; changing reproductive pattern is an unlikely contributor to the marked increase in incidence of NHL seen in many populations.

- Alternative splicing forms diverse mRNA isoform populations from a single ancestral pre-mRNA and thereby enhances complexity of transcript structure and of gene function. We describe a method called spliceotyping, which translates combinatorial mRNA splicing patterns into a library of binary strings of nucleic acid tags, encoding the exon composition of transcripts. The transcript abundance is registered by counts of individual molecules and individual exon inclusion patterns are represented as strings of binary data. The technique is illustrated by analyzing the splicing patterns of the adenovirus early 1A gene and the beta actin reference transcript. The method permits different genes to be analyzed in parallel and will be valuable for elucidating the complex effects of combinatorial splicing.

Unravelling the free electron behavior in InN

- Precise measurement of the optical Hall effect in InN using magneto-optical generalized ellipsometry at IR and THz wavelengths, allows us to decouple the surface accumulation and bulk electron densities in InN films by non-contact optical means and further to precisely measure the effective mass and mobilities for polarizations parallel and perpendicular to the optical axis. Studies of InN films with different thicknesses, free electron densities and surface orientations enable an intricate picture of InN free electron properties to emerge. Striking findings on the scaling factors of the bulk electron densities with film thickness further supported by transmission electron microscopy point to an additional thickness dependent doping mechanism unrelated to dislocations. Surface electron accumulation is observed to occur not only at polar but also at non-polar and semi-polar wurtzite InN, and zinc blende InN surfaces. The persistent surface electron density shows a complex behavior with bulk density and surface orientation. This behavior might be exploited for tuning the surface charge in InN.
